2006 BMW 3 Series fuel gauge.

Car: BMW 3 Series
Year: 2006
Variant: 320SE
Categories: Electrics, ECU, Warnings & Lights
When I fill the tank and the engine is off the gauge goes straight to the top "full". However when I start up the gauge drops back down to 1/4 tank?
Otherwise the mileage display, miles to go without filling up is ok.

Sounds like faulty fuel level sensor / tank unit , but a diagnostic scan should show fault .
